Embodiment Construction
[0063]In this embodiment, we describe an implementation of the technique described by means of a two-dimensional code. In this embodiment, a QR code version 4 or 10 is used to record the consolidated data (the data containing the payload data of the cash register receipt). Other types of QR codes can also be used. This is a simple presentation. The advantage of this type of QR code is that it can store 67 (version 4) to 395 (version 10) alphanumerical characters (an equivalent in bits can also be computed).
[0064]Depending on the embodiments, a code version 40 can also be used. The goal in this embodiment is not to store a link in the two-dimensional code, namely a link (or an address) towards which the cashing application of the payment terminal will be redirected to obtain the payload data. The goal is actually to store payload data in the code. Naturally, since the storage capacity of such a code is limited, just as the capacity of the cashing system to generate such codes is limi...
